Understanding Atrial Fibrillation Complexity Through the Lens of Turbulence Dynamics: Implications for Treatment Strategies

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 2, Page 400-412, February 2026.
ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these

Threshold Domain Sizes for Multifractality in Sea Ice Deformation

Geophysical Research Letters
Sea ice dynamics has long been studied in both engineering and geophysical contexts, but unifying these scales remains elusive. Multifractality in ice deformation is a key metric for validating large‐scale continuum models.

Quantifying long-range correlations and 1/f patterns in a minimal experiment of social interaction

Frontiers in Psychology, 2014
In recent years, researchers in social cognition have found the `perceptual crossing paradigm' to be both a theoretical and practical advance towards meeting particular challenges.

Higher Conformal Multifractality

Journal of Statistical Physics, 2003
We derive, from conformal invariance and quantum gravity, the multifractal spectrum f(alpha,c) of the harmonic measure (or electrostatic potential, or diffusion field) near any conformally invariant fractal in two dimensions, corresponding to a conformal field theory of central charge c.

The components of empirical multifractality in financial returns

, 2009
We perform a systematic investigation on the components of the empirical multifractality of financial returns using the daily data of Dow Jones Industrial Average from 26 May 1896 to 27 April 2007 as an example.

Exploring the Dynamic Interplay: Carbon Credit Markets and Asymmetric Multifractal Cross-Correlations with Financial Assets

Fractal and Fractional
This study investigates the multifractal characteristics and nonlinear cross-correlations between two major carbon credit indices—S&P Global Carbon Index and EEX Global Carbon Index—and key global financial assets: the Euro/US Dollar exchange rate, Dow ...

Multifractality of Pseudo-Velocities and Seismic Quiescence Associated with the Tehuantepec M8.2 EQ

Entropy, 2018
By using earthquake catalogs, previous studies have reported evidence that some changes in the spatial and temporal organization of earthquake activity are observed before and after of a main shock.
